[block][ahci] Remove barrier flags from driver

BLOCK_FL_BARRIER_BEFORE and BLOCK_FL_BARRIER_AFTER are
currently implemented in the block midlayer: if an incoming
operation has these barriers set, they will be used to
determine when operations should be enqueued to the underlying
driver. This logic is managed in dev/block/block/server.cpp,
and as a consequence, underlying drivers can process incoming
operations in any desired order.

[block][ahci] Interpret BLOCK_OP_ correctly and implement barrier flags

[pci] Remove lingering calls to pcie_read/pcie_write

ahci and bochs both use pcie_read & pcie_write for endianness handling
in reading registers. These functions are replaced by protocol methods
and only work with mmio, so they're being removed and these bochs/ahci
macros are replaced with the actual calls they were making.

[dev][ahci] use bti

This is a re-landed version of I76e114b9ea6123e7ef5fec390a7ef285e86cfd1e
(git commit 5d95f3a3404088560fff7dfa4ec53abd49877afc) which was reverted
in 335c3a414e169804eb9050d784af6cebd0f5c77f. The original patch passed
the wrong size to bti_pin, causing it to fail for non-page-aligned VMO
offsets. This has been tested on Acer12 and Paradise.

[pci] Rebuild kpci to use rpc and a proxy devhost

- pci_get_resource -> pci_get_bar
This is used for bars now that everyone is expected to use
pci_config_read for reading from their config.
- Removed PCI_BAR_[0-5] constants. Now that the only valid members
of the resource enum are bars it does not make sense to map
PCI_BAR_X to Xu and so on. Callers to the protocol can pass the
bar numbers directly now.
- pci_map_resource has been renamed to pci_map_bar
- zx_pci_get_config has been removed because it is obsolete
now that mapping is just for bars.
- zx_pci_get_bar has been refactored to manage the user handle
more cleanly thanks to Roland's change.
- Update some old code to call the pci_* protocol methods rather
than the device ops directly.
- Remove all privileged calls from the proxy devhost for pci
- Remove (nearly) all uses of the root resource from the proxy devhost
- Split kpci initialization into two disparate parts: the driver
that binds to the root complexes and creates upper devhosts,
and a proxy driver that creates lower/proxy devhosts for drivers
to interact with.
- Remove overlapping functionality in kpci and separate into two
proper driver "files".
- Ran clang-format on everything

[syscalls][ddk] Interrupt syscall improvements:

It is now possible to wait for multiple interrupts on a single interrupt handle.
The zx_interrupt_bind() syscall is used to bind an interrupt vector to
an interrupt handle, allowing up to 62 interrupt vectors per handle.

The zx_interrupt_get_timestamp() syscall can now be used to retrieve a
timestamp for an interrupt.

Virtual interrupts are now supported. zx_interrupt_bind() can be used to
designate an interrupt slot as a virtual interrupt, and the virtual interrupt
can be signaled using the zx_interrupt_signal() syscall.

The zx_interrupt_complete() syscall has been removed.
Instead, zx_interrupt_wait() now handles unmasking the interrupt
at the right time depending on whether the interrupt is edge or level triggered.

Slot ZX_INTERRUPT_SLOT_USER is reserved as a virtual interrupt, and is typically
used with zx_interrupt_signal() to unblock interrupt threads so they can exit
at driver shutdown or to perform periodic work.

Currently PCI interrupt handles can only be bound to a single interrupt vector,
but it is possible to bind virtual interrupts to PCI interrupt handles.
